    Well, as long as you don’t mind the clashing color balance. The needle LEDs turned out warmer than I expected, but Mary says she can cope. I should build a set of warm-white LED strips when it’s time to refit her real sewing machine and add another boost supply to drive them at their rated current.

    Much to our relief, the two LEDs at the needle don’t cast offensively dark shadows:
